Abstract: DESCRIPTION The NJM2180 NJM2180 is a TruSurround TM 3D Surround Audio Processor. It regenerates full surroundsound field with two speakers by internal TruSurround Virtualizer, when either 5.1 channels Dolby , Stereo function, and regenerates a 3D sound field with normal L/R input. In addition, the NJM2180 NJM2180 , Surround Audio Processors. It regenerates the full surroundsound field directly with any kind of surround encoded stereo signal input. The internal passive matrix circuits decode the surround encoded ...
